Al right dude , comeing right up ,
But I think this should be in the quailty images thread .

A+B=C-D=E
A is unknown weight
B is known weight
C is the sum of these two
D is the scale reading
E is the error
you add it up , then see if the scale reads the same +/- just a little

What is the resolution of this scale. I find it difficult to believe it is accurate to six digits. Generally a digial meter has a resolution of about 15,000 different weight values. IOW a scale rated up to 40,000 would measure in increments of maybe 3 pounds - ideal best. What is the resolution of that scale?

How can you add A + B, if A is unknown?

This scale has a cap of 500,000 lbs x 50 lbs ,
The Inspecter had me put it in 5 lb increments to exadurate the errors , not enough error to mention

That would be a 14 bit resolution scale - about right. Theoretical maximum resolution would be about 31 pounds.

That is a cool fucking job zippy, I am envious.

The thing I liked most about being a photog was meeting different folks and seeing different industries. I did a lot of work at GE plants. plastics, power, etc. never got boring. Just wicked long hours. 10 hours was a short day, 14 normal, 18 long...

How did you come up with that ???

The scale is rated for 10,000 counts leagle for trade .

Oh and Foot , one thing that I LOVE about my job is seeing all the different processes it takes to make the most inaquious things ,

zippyt · 12-10-2006, 08:30 PM

its what the scale says it is

xoxoxoBruce · 12-10-2006, 08:33 PM

Oh, ok...weight the unknown A, add the known B, and see if the scale changes by the known B.

Yeppers , what you are looking for is a known net weight change
